RESUMO

INTRODUCTION: Although Hematopoietic Stem Cell Transplantation (HSCT) is the only curative option for children with certain non-malignant disorders, a proportion of these children are admitted to the Pediatric Intensive Care Unit (PICU) due to treatment related life-threatening complications. AIMS: To analyze risk factors for ICU hospitalizations, morbidity and mortality in children with genetic diseases who have undergone HSCT and were admitted to intensive care units. METHODS: This retrospective study is based on the collection and analysis of clinical and laboratory data from the medical records of patients from the departments of Bone Marrow Transplantations and Intensive Care, from 2 hospitals, Hadassah and Rambam Medical Centers. RESULTS: Over the course of 15 years (2005-2019), 463 HSCT were performed for pediatric patients with non-malignant diseases, 68 of them (15%) required hospitalization in Intensive Care Units (ICU), 41% of the patients survived. The PICU mortality rate has decreased over the last years. Factors found to have a significant negative impact on PICU survival were severe neutropenia at admission to ICU, mechanical ventilation, inotropic support, and Multi Organ Failure (MOF). CONCLUSIONS: Our results showed low incidence of ICU admissions and relatively high survival rate for pediatric patients with non-malignant disorders post HSCT, comparing with literature data.

RESUMO

BACKGROUND: Although hematopoietic stem cell transplantation (HSCT) is the only curative option for some children with malignant and nonmalignant disorders, the procedure itself carries a high risk of complications. A proportion of children undergoing HSCT develop severe transplant-related complications requiring hospitalization in the pediatric intensive care unit (PICU). METHODS: A retrospective cohort study included 793 children with malignant and nonmalignant diseases that underwent 963 HSCTs in two large pediatric hospitals over 15 years. Ninety-one patients needed 105 (11%) PICU admissions. The objective of the study was to analyze the risk factors associated with morbidity and mortality in children post HSCT who were admitted to the PICU. RESULTS: Survival rate of a single PICU hospitalization was 43%. Long-term survival rate (classified as 1 year and 3 years) was 29.1% and 14.9% among PICU hospitalized patients compared with 74.6% and 53.3% among patients who had undergone HSCT and did not require PICU hospitalization. Factors found to have a significant negative association with PICU survival were respiratory failure as indication for PICU admission, neutropenia, graft-versus-host disease, mechanical ventilation, inotropic support, need for dialysis, and multiple-organ failure (MOF) with more than one systemic intensive intervention. The strongest prognostic factors associated with mortality were MOF (p < .001) and the need for inotropic support (p = .004). CONCLUSIONS: Neutropenia was found to be negatively associated with survival, suggesting non-engraftment and late engraftment are important risk factors for HSCT patients hospitalized in PICU. MOF and inotropic support were found to be the main negatively associated predictive factors with survival.

RESUMO

The European pediatric Soft tissue sarcoma Study Group analyzed all children with epithelioid hemangioendothelioma prospectively registered in the NRSTS-05 (EUDRACT 2005-001139-31) and in MTS-2008 (NCT00379457) studies: 10 patients with localized and one with metastatic disease. Median age was 14.3 years (range, 9.0-18.8). Local therapy was initial primary surgery in seven cases, and five patients received systemic therapy. No patients received radiotherapy. After a median follow-up of 50 months (range, 6-176) for living patients, nine patients remain alive off therapy and two died. Five-year progression free and overall survivals are, respectively, 77.1% (95% confidence interval [CI]: 34.5-93.9) and 74.1% (95% CI: 28.1-93.0).

RESUMO

OBJECTIVE. Percutaneous imaging-guided core needle biopsies (CNBs) for cancer diagnosis in pediatric patients are gaining interest because of their availability, lower rate of complications, and high diagnostic power compared with traditional surgical biopsies. Nevertheless, their precise role in the diagnostic algorithm of pediatric oncology is still unknown. The purpose of this study was to report our accumulated 16-year experience with CNB; discuss the availability, safety, and diagnostic accuracy of the procedure and the adequacy of ancillary testing; and compare our findings with the available literature. MATERIALS AND METHODS. Pediatric ultrasound-guided CNBs performed in our hospital between November 2003 and December 2019 were retrospectively studied. Data collection included demographics, clinical and procedural parameters, complications, and final diagnosis. RESULTS. A total of 597 biopsies were performed in 531 patients (132 performed in known oncologic patients and 465 performed to establish diagnosis). The median time between the biopsy request and the procedure was 1 day. Of 432 biopsies performed in patients with malignancies, 12 (2.8%) had false-negative results. In 165 cases of benign pathologic findings, all had true-negative results. Ancillary testing was adequate in all malignant cases. Overall sensitivity, specificity, and accuracy rates were 97.2%, 100%, and 98.0%, respectively. Five biopsies (0.8%) resulted in complications, including one major bleed and one track seeding. CONCLUSION. Our experience shows that ultrasound-guided CNB for suspected malignancy in pediatric patients has a high safety profile, availability, and accuracy rate compared with surgical biopsy. Our fast-track strategy enables early initiation of designated therapy and has the potential to become the procedure of choice.

RESUMO

BACKGROUND: Decisions on medication treatment in children dying from cancer are often complex and may result in polypharmacy and increased medication burden. There is no information on medication burden in pediatric cancer patients at the end of life (EOL). OBJECTIVES: To characterize medication burden during the last hospitalization in children dying from cancer. METHODS: We performed a retrospective cohort study based on medical records of 90 children who died from cancer in hospital between 01 January 2010 and 30 December 2018. Demographic and clinical information were collected for the last hospitalization. We compared medication burden (number of medication orders) at hospitalization and at time of death and examined whether changes in medication burden were associated with clinical and demographic parameters. RESULTS: Median medication burden was higher in leukemia/lymphoma patients (6 orders) compared to solid (4 orders) or CNS tumor patients (4 orders, P = 0.006). Overall, the median number of prescriptions per patient did not change until death (P = 0.42), while there was a significant reduction for some medication subgroups (chemotherapy [P = 0.035], steroids [P = 0.010]).Patients dying in the ICU (n=15) had a higher medication burden at death (6 orders) than patients dying on wards (3 orders, P = 0.001). There was a trend for a reduction in medication burden in patients with "Do not resuscitate" (DNR) orders (P = 0.055). CONCLUSIONS: Polypharmacy is ubiquitous among pediatric oncology patients at EOL. Disease type and DNR status may affect medication burden and deprescribing during the last hospitalization.

RESUMO

Metastasis most commonly occurs in the liver, lung, bone, and brain, implying its preference for specific organs. We hypothesized that organ microcirculation coagulation environment predisposes to tumor cell retention. Coagulation factors were analyzed using immunostaining, enzyme-linked immunosorbent assay, and heparanase procoagulant activity assay. In normal mice, expression levels of heparanase, tissue factor (TF), TF pathway inhibitor (TFPI), and TFPI-2 were low in the microcirculation of the liver, lung, brain cortex, and bone, and high in the microcirculation of the subcutis, skeletal muscle, brain subcortex, and bone marrow. C57BL/6 mice injected s.c. with B16 (F10) melanoma cells demonstrated lower levels of heparanase, TF, TFPI, and TFPI-2 in metastasis blood vessels compared to those in the primary tumor. In these mice with metastasis, liver and lung microcirculation turned to express high levels of coagulation proteins. Additionally, although mice with heparanase overexpression developed a larger primary tumor, they did not demonstrate a tendency for metastasis, as opposed to controls (P < 0.0001). Human umbilical vein endothelial cells, incubated with the B16 melanoma cell medium for 2 hours, expressed decreased levels of heparanase, TF, TFPI, and TFPI-2, and the effect was reversed by a peptide-inhibiting heparanase/TF complex interaction (P < 0.001). In summary, metastasis has a predilection to organs with low levels of heparanase, TF, TFPI, and TFPI-2 in the microcirculation, which enables tumor cell retention. Heparanase has a role in regulating the microcirculation milieu.

RESUMO

Nasopharyngeal carcinoma (NPC) is a rare and locally aggressive form of childhood cancer. Treatment of NPC includes chemotherapy and radiotherapy. With current treatment protocols, survival rates for patients with nonmetastatic disease is over 80%. Data regarding very late events including long-term treatment-related morbidities and second malignancies are scarce. We present our data on 42 patients with NPC treated in Israel between 1989 and 2014, and followed until 2019. During follow up, five patients had disease recurrence, and four children developed secondary malignancy. Median time to diagnosis of secondary malignancy was 105 months. Eighty-eight percent of patients have long-term treatment-related morbidities.

RESUMO

BACKGROUND: Therapy outcomes for childhood acute lymphoblastic leukemia (ALL) had substantially improved in the last decades, but variability across racial and ethnic groups was identified in some clinical studies. In this study, we aimed to investigate whether such a difference in outcome is found in the diverse ethnicities in Israel as well. METHODS: A retrospective study was conducted among 1154 patients (855 Jews, 195 Muslims, 52 Bedouins, 26 Druze, and 26 others) aged 1 to 21 years, who were diagnosed with ALL between 1989 and 2011 and were treated according to the same Berlin-Frankfurt-Muenster-based Israel National Study protocols. RESULTS: Bedouins had a higher incidence of t(1;19) (16% vs 3% for non-Bedouins) and a lower incidence of high-hyperdiploidy (10% vs 25% for non-Bedouins) (P = 0.01). Five-year event-free survival (EFS) and overall survival (OS) were poorer for the Bedouins (60.3% ± 7.2% and 63.1% ± 7.2%, respectively) compared with the Jews, Muslims, and Druze (80.4% ± 1.4%, 77.3% ± 3.2%, and 84% ± 7.3%, respectively, for EFS [P = 0.02], and 86.3% ± 1.2%, 82.3% ± 2.9%, and 88.3% ± 6.4%, respectively, for OS [P = 0.002]). Adherence to intensive chemotherapy was similar between the Muslims and the Bedouins. CONCLUSIONS: Our findings suggest that the Bedouins, a highly inbred ethnic Arab people, may be considered a higher risk group that may need more intensive chemotherapy and/or supportive care in order to improve their outcome.

RESUMO

BACKGROUND: For more than three decades, standard treatment for rhabdomyosarcoma in Europe has included 6 months of chemotherapy. The European paediatric Soft tissue sarcoma Study Group (EpSSG) aimed to investigate whether prolonging treatment with maintenance chemotherapy would improve survival in patients with high-risk rhabdomyosarcoma. METHODS: RMS 2005 was a multicentre, open-label, randomised, controlled, phase 3 trial done at 102 hospitals in 14 countries. We included patients aged 6 months to 21 years with rhabdomyosarcoma who were considered to be at high risk of relapse: those with non-metastatic incompletely resected embryonal rhabdomyosarcoma occurring at unfavourable sites with unfavourable age (≥10 years) or tumour size (>5 cm), or both; those with any non-metastatic rhabdomyosarcoma with nodal involvement; and those with non-metastatic alveolar rhabdomyosarcoma but without nodal involvement. Patients in remission after standard treatment (nine cycles of ifosfamide, vincristine, dactinomycin with or without doxorubicin, and surgery or radiotherapy, or both) were randomly assigned (1:1) to stop treatment or continue maintenance chemotherapy (six cycles of intravenous vinorelbine 25 mg/m2 on days 1, 8, and 15, and daily oral cyclophosphamide 25 mg/m2, on days 1-28). Randomisation was done by use of a web-based system and was stratified (block size of four) by enrolling country and risk subgroup. Neither investigators nor patients were masked to treatment allocation. The primary outcome was disease-free survival in the intention-to-treat population. Secondary outcomes were overall survival and toxicity. This trial is registered with EudraCT, number 2005-000217-35, and ClinicalTrials.gov, number NCT00339118, and follow-up is ongoing. FINDINGS: Between April 20, 2006, and Dec 21, 2016, 371 patients were enrolled and randomly assigned to the two groups: 186 to stop treatment and 185 to receive maintenance chemotherapy. Median follow-up was 60·3 months (IQR 32·4-89·4). In the intention-to-treat population, 5-year disease-free survival was 77·6% (95% CI 70·6-83·2) with maintenance chemotherapy versus 69·8% (62·2-76·2) without maintenance chemotherapy (hazard ratio [HR] 0·68 [95% CI 0·45-1·02]; p=0·061), and 5-year overall survival was 86·5% (95% CI 80·2-90·9) with maintenance chemotherapy versus 73·7% (65·8-80·1) without (HR 0·52 [95% CI 0·32-0·86]; p=0·0097). Toxicity was manageable in patients who received maintenance chemotherapy: 136 (75%) of 181 patients had grade 3-4 leucopenia, 148 (82%) had grade 3-4 neutropenia, 19 (10%) had anaemia, two (1%) had thrombocytopenia, and 56 (31%) had an infection. One (1%) patient had a grade 4 non-haematological toxicity (neurotoxicity). Two treatment-related serious adverse events occurred: one case of inappropriate antidiuretic hormone secretion and one of a severe steppage gait with limb pain, both of which resolved. INTERPRETATION: Adding maintenance chemotherapy seems to improve survival for patients with high-risk rhabdomyosarcoma. This approach will be the new standard of care for patients with high-risk rhabdomyosarcoma in future EpSSG trials.

RESUMO

BACKGROUND: It is currently expected that about 20% of children with cancer will ultimately die. Writing advanced life directives sufficiently long before the actual death of a child ensues allows both parents and medical staff to develop optimal treatment plans in the best interests of the child. AIM OF THE STUDY: The aim of the study was to evaluate factors that may influence the process of decision-making regarding Do-Not-Resuscitate (DNR) status. METHODS: Retrospective single institution study. RESULTS: Totally, 79 patients died between September 01, 2011 and August 31, 2017. Median age of the children was 10.5 years (range, 1 to 24 y). Forty-five were males. There were 37 Muslims, 27 Jews, 9 Druze, and 6 Christians. Twenty-one patients had sarcomas, 20 had CNS tumors, 10 had neuroblastoma, 17 had leukemias/lymphomas, 11 had carcinomas, and other rare tumors as well as nonmalignant diseases. No statistically significant association between all evaluated factors and DNR order status was found. CONCLUSIONS: It is possible that, other than demographic, clinical-associated, or therapy-associated factors play an important role in the process of decision-making regarding DNR. We feel that sincere communication between parents, their child (when appropriate) and medical and psychosocial staff may have a more crucial role when such decisions have to be made.

RESUMO

Medical marijuana (MM) is widespread in many medical fields, including oncology, with limited use in pediatric oncology where research is scarce and often shows conflicting results. This research focuses on alleviating side effects of anticancer treatment as an integral part of supportive and palliative care of children with cancer. We report our experience with MM treatment in 50 children, adolescents, and young adults with different types of cancer during 2010-2017. The main indications for prescriptions were nausea and vomiting, decreased mood, disturbed sleep, and pain. The medication was supplied to 30 patients via oil drops (60%) and 11 via smoking (22%), followed by vaporization, capsules, or combinations of various routes. Positive effects were reported by verbal children and parents in 80% of cases. MM was generally well tolerated with few patients reporting toxicity, with the most common adverse reactions being burning in the throat and anxiety attacks in subjects who chose to smoke the product. We conclude that MM may serve as a potentially useful complementary therapy to conventional supportive treatment of children suffering from cancer at the end of life. Further research is needed on the safety and efficacy and the consequences of prolonged use in pediatric populations.

RESUMO

BACKGROUND: Rhabdomyosarcoma is an aggressive tumour that can develop in almost any part of the body. Doxorubicin is an effective drug against rhabdomyosarcoma, but its role in combination with an established multidrug regimen remains controversial. Therefore, we aimed to evaluate the possible benefit of early dose intensification with doxorubicin in patients with non-metastatic rhabdomyosarcoma. METHODS: We did a multicentre, open-label, randomised controlled, phase 3 trial involving 108 hospitals from 14 countries. We included patients older than 6 months but younger than 21 years with a pathologically proven diagnosis of rhabdomyosarcoma. We assigned each patient to a specific subgroup according to the EpSSG stratification system. Those with embryonal rhabdomyosarcoma incompletely resected and localised at unfavourable sites with or without nodal involvement, or those with alveolar rhabdomyosarcoma without nodal involvement were considered at high risk of relapse. These high-risk patients were randomly assigned (1:1) to receive either nine cycles of IVA (ifosfamide 3 g/m2 given as a 3-h intravenous infusion on days 1 and 2, vincristine 1·5 mg/m2 weekly during the first 7 weeks then only on day 1 of each cycle [given as a single intravenous injection], and dactinomycin 1·5 mg/m2 on day 1 given as a single intravenous injection) or four cycles of IVA with doxorubicin 30 mg/m2 given as a 4-h intravenous infusion on days 1 and 2 followed by five cycles of IVA. The interval between cycles was 3 weeks. Randomisation was done using a web-based system and was stratified (block sizes of four) by enrolling country and risk subgroup. Neither investigators nor patients were masked to treatment allocation. The primary endpoint was 3-year event-free survival assessed by the investigator at each centre in the intention-to-treat population. Patients who received at least one dose of study treatment were considered in the safety analysis. In agreement with the independent data monitoring committee, the study was closed to patient entry on Dec 16, 2013, after futility analysis. This trial is registered with EudraCT, number 2005-000217-35, and is currently in follow-up. FINDINGS: Between Oct 1, 2005, and Dec 16, 2013, 484 patients were randomly assigned to receive each chemotherapy regimen (242 in the IVA group and 242 in the IVA plus doxorubicin group). Median follow-up was 63·9 months (IQR 44·6-78·9). The 3-year event-free survival was 67·5% (95% CI 61·2-73·1) in the IVA plus doxorubicin group and 63·3% (56·8-69·0) in the IVA group (hazard ratio 0·87, 95% CI 0·65-1·16; p=0·33). Grade 3-4 leucopenia (232 [93%] of 249 patients in the IVA plus doxorubicin group vs 194 [85%] of 227 in the IVA group; p=0·0061), anaemia (195 [78%] vs 111 [49%]; p<0·0001), thrombocytopenia (168 [67%] vs 59 [26%]; p<0.0001), and gastrointestinal adverse events (78 [31%] vs 19 [8%]; p<0·0001) were significantly more common in the IVA plus doxorubicin group than in the IVA group. Grade 3-5 infections (198 [79%] vs 128 [56%]; p<0·0001) were also significantly more common in the IVA plus doxorubicin group than in the IVA group, in which one patient had grade 5 infection. Two treatment-related deaths were reported (one patient developed septic shock and one affected by Goldenhar syndrome developed intractable seizures) in the IVA plus doxorubicin group, both occurring after the first cycle of treatment, and none were reported in the IVA group. INTERPRETATIONS: The addition of dose-intensified doxorubicin to standard IVA chemotherapy did not show a significant improvement in the outcome of patients with high-risk non-metastatic rhabdomyosarcoma. Therefore, the IVA chemotherapy regimen should remain the standard of care for patients with localised rhabdomyosarcoma in Europe.

RESUMO

Diffuse intrinsic pontine glioma (DIPG) is an incurable disease with a median overall survival of 10 months. Immune modulating antibodies have recently emerged as a highly promising treatment modality in multiple cancer types. We present results from the first study to evaluate the immune modulating antibody MDV9300 (pidilizumab) in pediatric patients with DIPG. All patients aged 3 years and older, diagnosed with DIPG between February 2014 and June 2015 in Israel, were offered to participate in the study. Enrolled patients were started on biweekly 6 mg/kg MDV9300 after radiation completion. Treatment was continued until disease progression on imaging. Patients were followed biweekly for the occurrence of neurological deficit toxicities and side effects. Secondary endpoints were event free survival and overall survival. Of 13 children diagnosed with DIPG during the study period, nine were enrolled in the study. The patients underwent radiotherapy and none had chemotherapy. A total of 83 cycles of MDV9300 (range 2-16) were applied. The main side effects were neutropenia (CTCAE grade 1-3), mild to moderate fatigue, and acute elevation of blood pressure. Four patients died within 1 year of the diagnosis, another three died within 2 years and two children are still alive nearly 30 months from diagnosis, with stable disease. The median event free survival is 9.3 months (range 6.8-24) and the median overall survival is 15.6 months (range 6.9-28). Preliminary results demonstrate that MDV9300 treatment is safe and may be effective in the treatment of children with DIPG.

RESUMO

The study explored the adjustment of Arab mothers of children diagnosed with cancer, as shown by the mothers' distress and quality of life. The aim was twofold: to examine the associations between educational level, psychosocial resources and adjustment indices and to assess the moderating effects of psychosocial resources on the education and adjustment association. The sample consisted of 100 Arab mothers who completed questionnaires assessing demographic and illness variables, mastery, social support, psychological distress and quality of life. High levels of education and psychosocial resources contributed to low distress and high levels of quality of life. Mastery and social support moderated the effects of education on adjustment: Under low levels of education, higher mastery was related to lower distress and higher quality of life, and higher social support was related to lower distress. Education, mastery and social support are important resources in the context of adjustment to cancer. In addition, psychosocial resources are important factors for adjustment under low levels of education and should be taken into consideration when developing intervention programmes for Arab parents coping with their child's cancer.

RESUMO

Nodular sclerosing Hodgkin lymphoma (HL) has an excellent prognosis in children. The syncytial variant (SV) of HL in adults represents a clinic pathologic entity with a worse outcome. We report the clinical features and the course of the disease of three children with refractory HL. The three patients with SV were analyzed in a retrospective multi-institutional study conducted in Israel in 51 children diagnosed with refractory or recurrent HL between 1997 and 2014. All the three children developed multiple recurrences soon after diagnosis. All three received at least three different chemotherapy combinations with autologous bone marrow transplantation for two patients, allogenic bone marrow transplantation in one, and immunotherapy in one. One patient died of disease, one is in complete response of the disease but developed a second metastatic malignancy, and one is alive without disease. This retrospective study shows that SV histology may be a prognostic factor for poor outcome in children diagnosed with HL.

RESUMO

Hematopoietic stem cell transplantation (HSCT) is the only proven curative option for patients with hemoglobinopathies, both thalassemia and sickle cell anemia (SCA). A busulfan-based myeloablative conditioning regimen is the standard of care for HSCT in these patients, although increased treatment-related morbidity, including veno-occlusive disease (VOD), has been demonstrated. Thirty-eight pediatric patients, median age 8 years (range, 6 months to 22 years), suffering from hemoglobinopathy were treated at Rambam Medical Center in Haifa, Israel, between 1998 and 2011. Thirty-four patients had thalassemia major and 4 had SCA. The 38 patients underwent 40 HSCTs, 34 of which were first transplants and 6 second transplants. Most transplants (32/40) were from matched sibling donors. Sources of stem cells were peripheral blood in 30 transplants, bone marrow in 7 transplants, and cord blood in 3 transplants. All received different customized busulfan-based conditioning regimens tailored by pharmacokinetic analysis of busulfan levels. Primary engraftment occurred in 37 of 40 transplants. Neutrophil engraftment (>.5 × 10(9)/L) occurred at a median of 15.3 days post-transplantation (range, 10 to 45). Platelet transfusion independence (>20 × 10(9)/L) occurred at a median of 22.3 days (range, 11 to 60). The rate of 5-year overall survival for thalassemia patients after first transplantation was 90.5% ± 5.3%. The rate of 5-year thalassemia-free survival was 81.7% ± 6.8%. Cumulative incidence of acute graft-versus-host disease (GVHD) was 17.6%. Rate of grades III to IV GVHD was 8.8%. Cumulative incidence of chronic GVHD was 23.5%, with 11.8% incidence of extensive chronic GVHD. One patient developed VOD. Full donor chimerism occurred in 36.4% of patients with class 1 + 2 thalassemia, compared with 78.6% in class 3 thalassemia (P = .049). Overall survival above 90% in patients undergoing their first transplant was demonstrated using busulfan-based conditioning regimens. The low incidence of VOD was probably due to busulfan area under the curve measurements and dose adjustment.

RESUMO

Both transplanted and leukemia patients are at high risk (HR) for invasive pulmonary aspergillosis (IPA). Methods for rapid diagnosis are crucial. Our objective was to investigate the impact of serial serum galactomannan assay (GMA) screening on IPA diagnosis in children. Between January 2010 and December 2011, all children following stem cell transplantation (SCT) or with HR leukemia were prospectively included. Serum samples for GMA were taken once-twice weekly. Results >.5 were considered positive. Patients suspected of having IPA were stratified as possible, probable, and definite. Forty-six children (median age, 8 years) were included, 38 after SCT (32 allogeneic), 8 with HR leukemia. A total of 510 samples were taken; screening period was 1-6 months for 34 patients. GMA was negative in 28 patients, all but one without suspicion of IPA. Eighteen patients had positive GMA: while four (22%) were upgraded to probable IPA, fourteen (78%) were considered as false positives (FP), some associated with piperacillin-tazobactam treatment. GMA sensitivity and specificity were 0.8 and 0.66, respectively; positive- and negative-predictive values (PPV, NPV) were 0.22 and 0.96, respectively. GMA may have a role in evaluating HR children for IPA. Both NPV and FP rates are high. The cost benefit of early detection versus over-diagnosis should be further studied.

RESUMO

OBJECTIVES: The goal of this study was to identify second opinion consultations by physicians and to determine patient and family factors that appeared to contribute to a second opinion being sought. METHODS: One hundred and fifty consecutive parents of children with cancer recently treated in our Department of Pediatric Hematology Oncology were interviewed by telephone. The questionnaire included epidemiological data, details about the disease, timing of the second opinion consultation, reasons for seeking a second opinion, and the outcome of the consultation. RESULTS: Thirty-seven (24.7%) parents sought a second opinion. Advice was sought from other physicians in the hospital or at other clinics. There was a correlation to a higher socioeconomic status (P = .003) and to the number of educational years (P = .001). Most of the parents sought a second opinion because they wanted confirmation about the treatment protocol and the professional level of the hematologist oncologist/surgeon and the institution. CONCLUSIONS: Second opinion consultations were not uncommon and were mainly secondary to the desire for reassurance. Pediatric oncologists should ensure that patients and their families feel comfortable requesting a second opinion consultation.

RESUMO

Rhabdoid meningioma is an aggressive phenotype of meningioma, associated with a poor prognosis. We present a very rare case of high-grade meningioma with rhabdoid features that eventually expressed in a coma state. Comprehensive genomic profiling using a Next Generation Sequencing (NGS) assay revealed three genomic alterations: activating BRAF mutation (V600E), loss of CDKN2A/2B, and APC I1307K. After treatment with BRAF inhibitor (dabrafenib), the child's clinical condition improved progressively. After seven months, an MEK inhibitor was added (trametinib).

RESUMO

BACKGROUND: The influence of socio-economic and religious background on decisions made by parents of children with incurable cancer regarding DNR orders is not fully understood. PROCEDURE: A retrospective analysis of medical charts of patients who died between January 2000 and January 2011 was performed. The following data were sought: written evidence of DNR discussion with parents, religious background, educational level, monthly income. RESULTS: There was evidence of a discussion on DNR in 73/90 charts. DNR consent was obtained in 14/17 (82.4%) cases where at least one parent had >15 years of education versus in only 24/45 (53.3%) cases where both parents had ≤15 years education as determined by univariate analysis (P = 0.03). DNR consent was also more likely to be obtained among parents of children with income >10,000 NIS (24/30, 80.0% vs. 20/38, 52.6%, P = 0.013). Parents of Jewish (22/30, 73.3%), Islamic (16/26, 61.5%), and Christian (8/9, 88.9%) background were equally likely to provide DNR consent. However, Druze families were less likely to do so (2/8, 25.0%, P = 0.036). CONCLUSIONS: The process of decision-making to a DNR request was associated with parents' educational level and monthly family income, and not by religious background, with the exception of Druze families.
